Spectroscopy
This technique has the potential to predict α-helix and β-sheet protein structures accurately and to predict other structures with a degree of accuracy previously achieved only with X-ray crystallography. The technique also has many advantages, including quick data acquisition, low sample requirement, and no special processing of raw data other than peak fitting.
